alterations to an existing tractor of standard design.

Another object is to provide such a device which may be operated by thepower of thetractor to which it is applied and under the completecontrol of the operator.

Another object is to provide such a device in which the shovel or scoop'may not only be elevated but also swung to either side so as to depositits load in a receiving truck which may be standing either to one sideof or directly in front of the device.

Further objects will appear from the detailed descriptiontaken inconnection with the accompanying drawings, in which:

A tractor is a device of varied utility and is used in many classes ofwork. such as grading and building operations, as well as some kinds ofexcavation work. Tractors of certain well known standard designs arefrequently athand or'available for use in such operations. An example ofsuch a tractor is the well known Fordson type. It

is a great convenience to have available a device which may be appliedwith little or no alterations to a tractor of such standard design, andwhich will adapt the machine for light digging operations and materialhandling operations. such as loading trucks in the transportat on ofbuilding materials. The present invention, as illustrated in thedrawings. is shown as applied to a Fordson tractor. The same isadaptable. of course, for any other type of tractor.

. pivots.

Referring now to the accompanying drawings, 1 designates generally thepower plant of the tractor which is suitably connected to an axle 2connected with traction wheels 3. The forward end of the power plant issupported on steering wheels 4 controlled in the usual manner by thesteering hand wheel 5 adjacent the drivers seat 6.

In accordance with this invention a suitable frame or chassis isprovided comprising a pair of side members 7 positioned laterally of thepower plant 1 and running along the same. These side members areconnected by means of any suitable connection such as the clamps 8 tothe rear axle 2 and are connected at their forward end by a cross-member9. The forward end of the frame is supported by a yoke or bracket 10carried by a pivot pin 11 engaging the front axle 12 and arranged topermit this axle to swing in a vertical plane so as to permit thesteering wheels 4 to accommodate themselves to inequalities of theground. The cross-member 9 at the front of the frame extends downwardlytherefrom and being suitably braced by gusset plates 13 or othersuitable means, is adapted to provide an abutment for en gaging theshovel 14 so as to propel the sdzincile for filling with the material tobe hani Pivoted at 15 is an upright derrick com prising a verticalcolumn 16 pivoted at its upper end at 17 to a suitable bracing structure18 connected in any suitable manner with the frame or chassis so as tosecurely brace the column 16 in upright position and permit the same toturn on its vertical Connected to the lower end of the column 16 andadapted to turn therewith is a forwardly and upwardly extending arm orboom 19 supported at its upper end by a bracing member 20 also connectedto turn with the column 16. The elements 16, 19 and 20 thus provide aderrick which is adapted to swing laterally about the pivots of thecolumn 16 and which is braced by the structure 18. Pivoted at 21 on theupper part of the derrick is a sliding shovel handle or stick 22. Thishandle provided with a longitudinally extending slot 23 which is adaptedto slide on the pivot 21 so that this handle is at the same timeslidably and pivotally mounted on the upper part of the derrick. Thehandle 22 is fixed at :24 to the shovel 14. At the shovel 14 is attacheda double block 25 adapted to run on a cable 26 secured at 27 to thehandle 22. The cable 26, being attached at 27 to the handle, passesunder a sheave 66 mounted to turn on the pivot 21, thence over a sheave67 on the upper end of the derrick. then down to one of the sheaves ofthe block 25, then up over one of a pair of sheaves 28, (only one ofwhich is seen in Figure 1), then down to the other sheave of the block25, then up to the other sheave of the pair 28, and then back to thepower plant as will be presently described. The shovel 14 is thussuspended on the forward part of the derrick so that when the cable 26is wound up. the shovel will be lifted and at the same time drawnforwardly, the forward movement being restrained, however, by a chain orcable 68 connecting the shovel 14 with the upper part of the column 16.The handle 22 is adapted during such movement to slide on the pivot 21and guide the movement of the shovel 14.

A tractor of the type here illustrated is ordinarily provided with anauxiliary shaft 29 connected with the motor so as to provide means fordriving auxiliary apparatus. In accordance with the present invention,the shaft 29 is connected by means of suitable gearing, such as the wormgearing 30, with a horizontal shaft 31 mounted in suitable bearings 32on one of the side members 7. Mounted on the shaft 31 is a Winding drum33 adapted to wind the cable 26, which after passing over the secondsheave 28,

passes back between a pair of sheaves 34 mounted on the upper part ofthe structure 18 and so positioned that the cable 26 will be guidedthereby from the sheave 28 to a sheave 35 mounted on the structure 18 inwhatever position the derrick may take in swinging about its verticalpivot. From the sheave the cable 26 passes over a sheave 36 on thestructure 18 and then down to the drum A suitable clutch 37 is pro videdfor connecting the drum 33 to the shaft 31 when it is desired to wind upthe cable 26. The clutch 37 is controlled by an operating handle 38positioned adjacent the drivers seat 6 and connected by a suitableconnection 39 so as to operate a brake 40 on the drum The handle 38 isso connected to the clutch 37 and the brake 40 that when the clutch isin engagement so as to connect the drum with the shaft 31, the brake 40will be free. When, however, the clutch is released, the brake 40 isset, but a very slight interval is provided between the position of thearm 28 at which the clutch is released and the position at which thebrake 40 is engaged. This arrangement is to provide for lowering theshovel 14. The shovel is permitted to come down by its own weight butunder the control of the brake 40, the operator controlling the handle38 so as to regulate the pressure of the brake 40 in such a way as tocontrol the speed of descent of the shovel and to stop the same at thedesired point.

In order to provide for swinging the derrick laterally so as to swingthe shovel to either side for loading trucks, an arcuate rim or guide 41is suitably mounted on the column 16. A cable 42 is suitably fixed tothis guide 41 to turn the same for turning the derrick. This cable isfixed at 43 to one side of the guide 41, passes part way around saidguide to the opposite side to a sheave 44 mounted on the structure 18,thence to a sheave 45 and a sheave 46 also mounted on the structure 18to a small traction drum 47 on the shaft 31. The cable passes severaltimes around the drum 47 and then ofi of said drum over a sheave 48 anddown to a second drum 49 similar to the drum 47.

The cable passes several times around the drum 49 and then ofi" of saiddrum to a sheave 50, thence to a sheave 51 mounted on the structure 18on the opposite side to the sheave 44, and then back around the guide 41being fixed thereto at 52 at the opposite side thereof to the point ofattachment 43. The drums 47 and 49 are individually controlled byclutches 53 controlled by an operating handle 54 pivoted at 55 on theframe and arranged so that when one clutch is engaged, the other isreleased. The drum 4? is further provided with a brake 56 connected byasuitable connection 57 with the operating handle 54. The arrangement issuch that when the handle 54 is in mid-position, both of the clutches 53are released and the brake 56 is set. When the handle 54 is moved eitherforward or back, one or the other clutch 53 is engaged and the brake 56is released. By means of the handle 54, therefore, the operator hascontrol of the swinging of the derrick from side to side. By moving thehandle forwardly, the brake 56 is released and one of the drums 47 or 49is operated by the shaft 31. At the same time, the other drum is free torotate idly on said shaft. By this arrangement the cable 42 may bepulled in one direction by the active drum so as to swing the derrick tothe side desired. As soon as the handle 53 is returned to mid-position,both drums are released from the shaft 51 and the brake 56 is set. tatethe drum 47 which consequently holds the cable 42 against movement andthus holds the guide 41 and consequently the derrick in the position towhich it has been swung.

Additional means for locking the derrick against swinging movement areshown in Figurcsl. 4 and 5. Mounted on the cross members 69 and 70 is apair of levers 71 and 72 provided with brake shoes 73 and 74 adapted toengage the guide 41. The levers are connected near their forward ends bya This renders it impossible to rolink and are secured against lateralmovement by being let into a notch 76 in the member 69 and beingconfined between guide strips 77 on the structure 18. The rear ends ofthe levers 71 and 72 are connected by a toggle 78 to the middle point ofwhich a link 79 is connected. The link 79 is connected to a platepivoted on the structure 18- andconnected by a link 81 to thebooom-swing handle 54. The connections are such that when the handle 54is in neutral position the toggle 78 is spread so as to clamp the shoes73 and 74 against the guide 41 to hold the same againstmovement.

In orderto start the engine, the shaft thereof is connected by means ofa suitable sprocket and chain connection 58 to an auxiliary shaft 59suitably mounted on one of the side members 7 and connected by means ofa pair of bevel gears 60 to a crank 61. This connection enables theoperator to start the engine from the side since the mounting of thederrick in front makes a connection in front impossible.

In operating this device the tractor may first be operated as a vehicleto carry the device to any desired point at which it is to be used. Inorder to pick up its load, the operator will release the drum 33 andallow the shovel to descend under the control of the drum 40. Duringthis operation the handle 22 is extended and at the same time depressedso as to position the shovel 14 in front of the abutment 9 and in such aposition that its digging edge or prongs 62 will engage the ground orthe material to be handled. The operator will then drive the tractorforward by means of its traction wheels 3, so as to propel the shovelforwardly to fill the same with material. lVhen thus filled the tractormay be stopped and held stationary while the handle 38 is oper-' ated tolift the shovel. By the lifting operation, the cable 26 being suspendedfrom the forward part of the derrick draws the shovel forwardly andupwardly. downward pull of the cable 26 on the handle 22, to which it isconnected at 27, assisted by the weight of the parts, resists retractionof the handle during the early part of the shovel movement'and producesan outward thrust along the handle to keep the shovel in extendedposition during its upward movement. The outward movement of the handleis restrained by the chain 68 which is kept taut during said movement.

At the same time the handle 22 operates to guide the shovel in a forwardand upward scooping movement adapted to gather up the material and atthe completion of this movement, the shovel 14 is righted, so as toretain the material therein. During the elevation of the shovel. thehandle 22 is retracted by the chain 68 by a sliding movement duringwhich the slot 23 moves over the pivot 21.

The

This retractive movement of the handle 22 is also effected by thelifting cables 26 which change their angle with respect to the handle asthe shovel rises until, at the end of the movement. they are in aposition to actually retract the shovel. When elevated. the shovel takesthe position illustrated in Figure ,2. The operator may now operate thehandle 54 so as to swing the derrick and with it the shovel laterally soas to be able to deposit its load on either side of the tractor. hen theshovel has been suitably positioned over the receiving vehicle. the pullrope 63 may be operated to release the latch 64 so as to open the bottom65 of the shovel and deposit the load. Having deposited the load, theoperator again moves the handle 38 so as to release the brake 40 andallow the shovel to'descend under the control of the brake. again closesand when the same is brought against the abutment 9, the latch 64 willcatch to hold the same closed.

In accordance with this invention, therefore, a machine is'provided bymeans of which the handling of materials is readily facilitated. It isnot onlycapable of transporting itself to the place at which it is to beused, but provides power driving means for picking up and depositingmaterials as desired. The shovel may be positioned so as tobe/pr'opelled by the tractor itself for gathering up its load and maythen be lifted and swung laterally so as to deposit the load as desired.This makes it possible to use this device not only in handling materialsbut in certaindigging or excava ing opera tions. The structure isarranged so that it may be easily and quickly applied to a tractor ofpresent standard design with a minimum of alteration in the tractor.There is thus provided a simple and effective device which may beapplied to a tractor of provcn reliability to adapt the same for a widerfield of use.

It is obvious that various changes may be made in details ofconstruction without de parting from the spirit of this invention: itis, therefore, to be understood that this in- During the descent thebottom llO vention is not to be limited to the specific details shownand described.
